1. It is also possible to generate a circular fine about the midpoint of a line The line is specified by endpoints 1 2 A fan may be drawn using the midpoint of four markers as well Here s what it looks like on an organism fan A fish And despite the obvious relevance I was unable to come up with a Red Wings Fan Pesky Details Use the File menu to load and save images Saved files are always tiff format The Number of Lines controls the numbers of lines in the fan The Exaggeration controls the line length An exaggeration of 1 draws from point 1 to the midpoint Larger exaggerations increase the line length Experiment e Makefan6 can digitize points but is not recommended Use TPSDig Still More Details You can increase the line weight of the fan using an option on the Image menu Zoom functions are also on the image menu Be careful when zooming at the moment you can foul up the aspect ratio it can be reset using an option on the image menu You can also remove a marker point placed on an image by using the option in the image menu Using the MakeFan6 image processing Tool H D Sheets August 2002 sheets canisius edu 1 Expand MakeFan6 into the same directory as the rest of your IMP software which should be the subdirectory bin win32 Try starting MakeFan If it does not load correctly or step 2 below fails obtain the file2. EXTRADLL EXE from the website and expand it into the bin win32 directory with the rest of your IMP software I am trying to clean this up so it isn t such a hassle but no luck yet 2 Load an image into MakeFan using the File menu on MakeFan MakeFan will load jpeg tiff or bitmap bmp Tiff seems to be the most reliable 3 Place your markers 1 2 3 4 as desired to create fans Use the different Fan options to create different fans Plan on spending some time experimenting with the fans to figure out what you will need to use 4 When you have a fan placed use the File option on the MakeFan window to save TIFF JPEG or BITMAP images with the fan on them to disk MakeFan works with only one image per file 5 If you load a new image into MakeFan it will replace the prior image Make Fan does have the ability to digitize landmarks although it is not as good a program for this as TPSDig I haven t written a manual for these operations of MakeFan but feel free to mess around with it To start digitizing click on the Place LM button then position the cursor and click to place landmarks Each landmark will be numbered To stop placing landmarks move the cursor to the far lower right of the screen not on the EXIT button please and click there off of the image The cross hairs should then shut off The button DEL LAST LM will delete the last landmark you placed If you hit the place landmark button again you can start placing landma
3. MakeFan H David Sheets sheets canisius edu This is a very rough user s manual for MakeFan it will eventually be replaced with something a bit more polished MakeFan draws fans which are radial guidelines with equal angular spacing on images tiff jpeg or bitmap of specimens to aid in digitizing points along curves or contours This approach is intended to be used in conjunction with semi landmark methods utilizing the SemiLand6 program Obtain a copy of SemiLand6 if you haven t already and read the files SemiLand6_manual and Semi Land_becki included with it as well The first section of this manual is the pdf form of a PowerPoint presentation on MakeFan I wrote for a workshop on morphometrics at Berkeley in June 2002 The comment about the Red Wings is a joke about Miriam ask her what it means when you meet her Following the Power Point derived material is a short set of instructions on how to run MakeFan Using Make Fan What is a fan and why do I need one How do you use MakeFan6 Digitizing within MakeFan6 A fan 1s a graphical tool for picking out points to digitize along a curve Placing a fan on an image Load the image into Makefan tiff jpeg bitmap Place one or more fans Save the image with fans as t1f eDigitize in TPSDig Specifying the type and location of a fan Triangular or Circular End points of the fan eMid point of the fan Length of the fan Line Weight mid point
